Can't create disk space utilization graph

[omurad]

I have added multiple Linux servers using the the passive Linux template, which links to the filesystem module.

When I go to Monitoring->Latest Data, I can see lines displaying filesystem utilization data, and a button to view its graph.

However, when I go to create a dashboard widget, I can display CPU and memory utilization but not disk utilization.

Why does disk space utilization not show up as an option? How can I create a disk space utilization graph on my dashboard?

I was able to add the graph via the Graph (classic) widget and searching for the prototype created graph.
